Question

each gamete produced has a different combination of genes from the organism. what causes these different combinations? a dna replication prior to mitosis b chromosomal replication during mitosis c dna transcription and translation d independent assortment during meiosis

Explanation:

During meiosis, independent assortment of homologous chromosomes occurs. This leads to different combinations of maternal and paternal chromosomes in gametes, resulting in unique gene combinations in each gamete. Mitosis - related processes (A and B) maintain genetic consistency and DNA transcription/translation (C) is for protein - synthesis, not for generating gamete gene - combination diversity.

Answer:

D. Independent assortment during meiosis
